Cards shipped from the end of March, 2013 to August, 2013 are potentially affected by the problem.

Problem Description

In some situations, the insertion of the 15454-M6-ECU or 15454-M6-ECU2 unit in the M6 chassis might require additional force. Therefore, the software might not detect the units because the back-plane connector does not completely engage with the mate that is mounted on the M6 chassis.

Background

Cards that were built between March, 2013 and August, 2013 use a back-plane connector that might require a higher insertion force due to production variability. Once properly inserted, these cards work and behave properly so no further actions are required. Cards manufactured outside of this time-frame are not impacted by this Field Notice.

Problem Symptoms

The insertion of the unit is completed easily up to 2 mm (1/10 of an inch) of the complete seating. From this point, additional force might be required for the proper mating of the back-plane connectors. If this additional force is not applied, the unit does not install properly and the software does not detect it.

Workaround/Solution

As a workaround, apply more force in order to plug the unit into the chassis. In order to perform a functional sanity check, connect an RJ45 Fast Ethernet cable to the RJ45 port of a PC (not under the same Network IP domain). If the green LED indicator illuminates, the card is correctly plugged-in.

Here is a picture with a comparison between a partial insertion versus a complete insertion.

How To Identify Hardware Levels

The Serial Number Validation Tool identifies the units that are potentially affected by this problem. If you experience difficulties with the insertion of an ECU unit, insert the serial number of the unit into the tool in order to verify if it is impacted by this problem.

The serial number of the ECU unit is retrieved from the ECU unit itself or the box from which the unit is shipped.
